1、Arduino与电脑和蓝牙模块通讯都使用串口TX/RX,同时操作时产生冲突,程序写入Arduino时要断开与蓝牙相连的RX。 2、 执行时要注意,Serial.println()会将内容输出到蓝牙的另一端,而不是在电脑端显示信息。 3、蓝牙的默认密码是0000或1234。 4、如果外接驱动模块L298n时,需要将模块L298n和Arduino连接在同一电源上,...

Arduino Due is the most powerful Arduino development board in the Arduino series. This Arduino board is a beginner board including many features with excellent processing speed, so used in advanced applications. This board was developed on an ARM series controller whereas other Arduino boards were ...

See the description of digital pins for details on the functionality of the pins. As of Arduino 1.0.1, it is possible to enable the internal pullup resistors with the mode INPUT_PULLUP. Additionally, the INPUT mode explicitly disables the internal pullups. Syntax pinMode(pin, mode) ...
